The National Wildlife Refuge System is a network of protected areas in the United States dedicated to conserving wildlife and their habitats. Established in 1903, it aims to provide safe environments for various species, including endangered ones, while also offering recreational opportunities for the public. The system is managed by the U.S. Fish and Wildlife Service. Comprising over 560 refuges and 38 wetland management districts, the system spans millions of acres across the country. These areas support diverse ecosystems, from wetlands to forests, and play a crucial role in preserving biodiversity. The refuges also promote environmental education and wildlife observation.
